Black Market

Summary

Players can access the Black Market from the Thieves Guild menu
On the Black Market, players will see listings for each Rarity Level of Black Goods and buttons to exchange Black Goods of that Rarity Level for a random item
The random items players can receive from Black Goods include Gold, Arcane Essence, all Special/Rare items available from normal loot tables (Arcane Scrolls, Skill Mastery Scrolls, Mastercrafting Diagrams, etc), Thief Hue Items (Cloth, Dyes, Lanterns, Footwear, etc) and Thief Antiquities
An Expected Gold Value for each Rarity Level shows the player how much Gold they would likely receive when doing an Exchange for that Rarity Level this week if they received Gold as their random item

At the start of every week a "Weekly Scarcity" for each Rarity Level is determined, based on the number of total Black Goods all players combined turned in for that Rarity Level in the previous week compared to the week prior to that
Weekly Scarcity for each Rarity Level will range between -50% to +50% depending on the difference in amounts turned in between the different weeks
When players Exchange Black Goods of a Rarity Level, the Weekly Scarcity for that Rarity Level will impact how much Gold is received as well as adjust the chances for the player to instead receive a Special / Rare / Unique items rather than Gold
A Timer in the bottom left section of the menu indicates when Weekly Scarcity levels will next be recalculated and Updated

Players can use the Left/Right arrows in the bottom panel to choose where they Exchange Black Goods from (their Bank or Backpack), how many (1 or All), and where they wish to receive the new items (Backpack or Bank Box)
Players will receive a system message for each item that they receive when Exchanging Black Goods
If the player elects to Receive in Backpack, any gold they receive will be automatically placed into an existing or new Bank Check in their backpack (otherwise players will likely never be able to hold the weight of the gold they receive)
If a player does not have enough room in their Backpack, it will not complete any Exchange for that item (and will stop if doing All in Backpack)
If the player elects to Receive in Bank Box, any gold they receive will be Deposited as normal, and all items will be placed if room exists or Queued into their bank box if room does not exist
